Changes and events over life course: a comparative study between groups of older adults

OBJECTIVE:

to identify the changes which had occurred over the last year in the life of older adults, as well as the values attributed to these changes.

METHOD:

this is a multicentric, cross-sectional study, of the inquiry type, undertaken in three cities of the Brazilian Northeast, investigating two distinct groups of older adults.

RESULTS:

among the 236 older adults interviewed, it was observed that 30.0% reported health as the main change in their life course in the last year, this category being the most significant response among the older adults aged between 80 and 84 years old (37.7%). Changes in the family were mentioned by 11.5% of the older adults; death (9.6%) and alterations in routine activities (9.6%). In relation to the value attributed to these changes, it was ascertained that for 64.7% of the older adults aged between 65 and 69 years old, these changes were positive. In the older group, 49.4% of the older adults believe that their changes were related to losses.

CONCLUSION:

the knowledge of the changes mentioned, the value attributed to these changes, and the self-evaluation of health provide information which assists in formulating actions which are more specific to the real needs of these age groups. They also provide the health professionals with a better understanding of how some experiences are experienced in the life trajectories of these older adults.

The role of plasmapheresis in critical illness

In this article, the authors review the current recommendations from the American Society for Apheresis regarding the use of plasmapheresis in many of the diseases that intensivists commonly encounter in critically ill patients. Recent experience indicates that therapeutic plasma exchange may be useful in a wide spectrum of illnesses characterized by microvascular thrombosis, the presence of autoantibodies, immune activation with dysregulation of immune response, and some infections.     

Health services performance for TB treatment in Brazil: a cross-sectional study

ABSTRACT: BACKGROUND: Researches to evaluate Primary Health Care performance in TB control in Brazil show that different cities aggregate local specificities in the dynamics of coping with the disease. This study aims to evaluate health services' performance in TB treatment in cities across different Brazilian regions. METHODS: This cross-sectional study was conducted in five cities that are considered priorities for TB control in Brazil: Itaboraí (ITA), Ribeir?o Preto (RP) and S?o José do Rio Preto (SJRP) in the Southeast; Campina Grande (CG) and Feira de Santana (FS) in the Northeast. Data were collected through interviews with 514 TB patients under treatment in 2007, using the Primary Care Assessment Tool adapted for TB care in Brazil. Indicators were constructed based on the mean response scores (Likert scale) and compared among the study sites. RESULTS: "Access to treatment" was evaluated as satisfactory in the Southeast and regular in the Northeast, which displayed poor results on 'home visits' and 'distance between treatment site and patient's house'. "Bond" was assessed as satisfactory in all cities, with a slightly better performance in RP and SJRP. "Range of services" was rated as regular, with better performance of southeastern cities. 'Health education', 'DOT' and 'food vouchers' were less offered in the Northeast. "Coordination" was evaluated as satisfactory in all cities. "Family focus" was evaluated as satisfactory in RP and SJRP, and regular in the others. 'Professional asking patient's family about other health problems' was evaluated as unsatisfactory, except in RP. CONCLUSIONS: Two types of obstacles are faced for health service performance in TB treatment in the cities under analysis, mainly in the Northeast. The first is structural and derives from difficulties to access health services and actions. The second is organizational and derives from the way health technologies and services are distributed and integrated. Incentives to improve care organization and management practices, aimed at the integration of primary, secondary and tertiary services, can contribute towards a better performance of health services in TB treatment.     

Tuberculosis among health care workers in a Brazilian tertiary hospital emergency unit

The Brazilian emergency system is being reorganized as a hierarchy in the region of Ribeirão Preto, state of São Paulo. We found increased occupational risk for tuberculosis in this region tertiary reference center—a nurse technician (Incidence rate [IR] 526.3/100 000 inhabitants) had a risk of tuberculosis 12.6 (95% confidence interval [CI], 2.57-37.23) greater than the city population (41.8/100 000 inhabitants). The system reorganization will have to make the centers adequate to deal with this problem.     

Substance use among a sample of foreign- and U.S.-born southeast Asians in an urban setting

Asian Americans (AA) are thought to have the lowest rates of substance use. This study examined substance use prevalence among 494 urban-dwelling Southeast Asians using snowball techniques. Prevalence estimates were age-adjusted proportionate to the U.S. Asian population. Findings show beer and alcohol consumption approximated the national percentage among 25-44 year olds. U.S.-born were about three times likelier to have past month substance use. Foreign-born Vietnamese were likelier than U.S.-born to use all substances except for beer. U.S.- and foreign-born beer consumption rates were similar. Future research is needed to delineate substance use determinants and patterns in foreign and U.S.-born AA sub-groups.     

Peanut allergy: Beyond the oral immunotherapy plateau

BackgroundThere are a lack of disease‐modifying treatments for peanut allergy, which is lifelong in most instances. Oral immunotherapy has remained at the forefront of prospective treatments, though its efficacy is consistently undermined by the risk of adverse reactions and meager sustained effects.AimThis review discusses the current state of oral immunotherapy, its strengths and limitations, and the future of therapeutics for the treatment of peanut allergy.ConclusionThe persistence of peanut allergy is currently attributed to reservoirs of peanut‐specific memory B cells and Th2 cells, though the cellular and molecular interplay that facilitates the replenishment of peanut‐specific IgE remains elusive. Uncovering these events will prove critical for identification of novel targets as we forge ahead to a new age of peanut allergy treatment with biotherapeutics.     

Applicability of an optimized non-conventional flow cytometry method to detect anti-Trypanosoma cruzi immunoglobulin G for the serological diagnosis and cure assessment following chemotherapeutic treatment of Chagas disease

One of the challenges on immunodiagnostic of Chagas disease in endemic areas has been the search for more practical and safe antigenic preparation that provides tests with higher sensitivity and specificity, with low cross-reactivity. A new approach using fixed Trypanosoma cruzi epimastigotes to detect IgG reactivity was investigated previously. In order to continue this investigation, this study aimed at optimizing the flow cytometry-based method to the diagnosis of Chagas disease patients after specific chemotherapy. To achieve our goal, serum samples from 93 subjects - 52 adults chronically infected by T. cruzi, and 41 uninfected controls were tested by flow cytometry. Secondly, serum samples from patients Treated Cured and Treated Uncured from Chagas disease were also tested to evaluate the potential of the method on assessing cure. After establishing the ideal serum dilution and cut off, 121 serum samples from patients with other endemic infections were tested to check cross-reactivity. The results showed that parasite staining with Evan's blue dye eliminated debris, allowing trustworthy analysis of anti-fixed epimastigote IgG reactivity. The applicability of the method to diagnose Chagas disease was confirmed by the high sensitivity (98.1%) and specificity (100%) found. This method also contributed for post-therapeutic assessment of cure, identifying 94.1% of Treated Uncured and 83.3% of Treated Cured patients. Cross-reactivity was observed in a very low number (6.7%). On the whole, these data highly recommend the use of anti-fixed T. cruzi epimastigote IgG reactivity by flow cytometry to the diagnosis and cure monitoring of Chagas disease in endemic areas.
